Definitions

  • the primary aspect of the invention is to provide a multi-axle vehicle suspension system having at least two torsion axles, each torsion axle coupled to a vehicle frame, and further having a pivotal member pivotally coupled to the vehicle frame and pivotally coupled to each torsion axle.
  • FIG. 3 is an upper view of the inventive suspension system.
  • FIG. 1 shows one side of a vehicle suspension, a like arrangement being present on the other side of the vehicle.
  • the theoretical direction of travel for the frame is D.
  • a suspension pivot member 200 is pivotally coupled to mount F 2 .
  • the other end of the suspension pivot member is pivotally coupled to a coupling member 201 .
  • Coupling member 201 is also pivotally coupled to pivot member 1000 .
  • a torsion axle assembly 400 is installed in suspension pivot member 200 . Torsion axle assembly 400 is described in FIG. 4 . A wheel and tire combination W 2 is rotationally mounted to the axle assembly at CL 2 .
  • suspension absorbs movement of axles A 1 and A 2 by movement of each of the suspension pivot members 100 and 200 , as well as by the pivoting movement of pivot member 1000 .
  • Pivot member 1000 pivots on mount F 1 to further absorb and transmit differential movement of the two axle assemblies 300 , 400 .
  • FIG. 2 is a lower perspective view of the inventive suspension system.
  • Two torsion axles 300 , 400 are shown mounted to suspension pivot members 100 , 200 , respectively.
  • Axle 300 comprises a spindle 301 and spindle 302 on opposite sides of the axle.
  • Axle 400 comprises a spindle 401 and spindle 402 on opposite sides of the axle.
  • Wheel W 1 is attached to spindle 301 .
  • Wheel W 2 is attached to spindle 401 .
  • a wheel is also attached to each spindle 302 and spindle 402 .
  • each pivot point P 8 and P 9 along the length of each suspension pivot member 100 and pivot member 200 respectively.
  • Pivot point P 8 may be located to one side or the other of the suspension pivot member 100 along its length as shown in FIG. 1 , or it may be centered in suspension pivot member 100 as well.
  • Pivot point P 9 may be located to one side or the other of the suspension pivot member 200 along its length as shown in FIG. 1 , or it may be centered in suspension pivot member 200 as well.
  • pivot points P 8 and P 9 need not be located in the same relative position on each respective suspension pivot member.
  • each spindle 301 and spindle 401 is approximately centered between each pivot point P 1 , P 2 and P 5 , P 7 respectively.
  • FIG. 4 is a detail of the torsion axle.
  • the torsion axle comprises a plurality of rubber cords disposed within an axle member, and a torsion member situated within the axle member by the rubber cords, and finally, the torsion member connected to a spindle for mounting a vehicle tire.
  • Each torsion axle 300 and axle 400 comprises the arrangement described herein for each vehicle tire.
  • spindle 301 is attached to torsion arm 303 .
  • Torsion member 304 is attached to torsion arm 303 .
  • Torsion member 304 is rectangular or square in cross-section.
  • Torsion member 304 is disposed within an axle member 306 receiving portion 307 .
  • Axle member 306 has a rectangular or square cross-section.
  • Also disposed within axle member 306 is a plurality of rubber cords 305 . Rubber cords 305 are of a sufficient size and are disposed between the torsion member 304 and axle member 306 in a manner which counters rotational movement of torsion member 304 when a load is applied to the spindle 301 . In the preferred embodiment there are four rubber cords 305 .
